A woman is found murdered in the middle of Øresund Bridge – right on the border between Sweden and Denmark. Saga Norén from Malmö CID and Martin Rohde from the Copenhagen police department are called to the scene. What at first looks like one murder, turns out to be two. The bodies have been brutally cut off at the waist and joined together – the torso of a high-profile Swedish politician and the lower body of a Danish prostitute.

The murderer makes his presence known and chooses the sharp-witted tabloid journalist Daniel Ferbé to act as a middle man in his communication with the outside world. It turns out that the murder on the bridge was only the beginning, and that the purpose of that heinous act was to draw attention to the unpleasant truths and problems in our society that we have chosen to turn a blind eye to, the first one being that “we are not all equal before the law”. Saga and Martin now realise they are dealing with a ruthless killer who has been planning his crimes for many years. At the same time, Martin faces problems at home where he is in constant conflict with his son August who has just moved home.

In Copenhagen, several homeless people have been poisoned to death. The perpetrator wants to draw attention to the problem of the increased number of people falling through the cracks of society. A homeless man is kidnapped and the only thing that can stop the murderer from killing him is a large sum of money from four landlords. So what is the price of a human being after all?

The homeless man's survival becomes a race against time, and depends completely on the four landlords' willingness to pay what the murderer demands. Saga and Martin have understood that they're dealing with someone who has really thought through his crimes, planning them down to the smallest detail. Maybe they can catch the murderer off balance by doing something he doesn't expect?

The murderer has groomed a number of seriously schizophrenic people over a long period of time, convincing them to commit carefully synchronised violent crimes in Malmö and Copenhagen on the same day. With the third truth, the murderer wants to highlight the cutbacks within mental health care, which has been reduced to “a pat on the back and a jar of pills”. Saga and Martin manage to find a break in the case, a teenage girl who has run away from home. Could she be the witness that ultimately leads them to the murderer?

Copenhagen is up in arms following a court case in which a group of police officers that beat an immigrant to death are found innocent. One of the accused officers is kidnapped from his home and is found by the dead immigrant’s brother chained up in his basement. Will he forgive or take revenge on his brother’s killer? Here the murderer wants to draw attention to the fourth truth, namely the failure of the state’s integration policy. For the first time Saga and the killer are in contact with each other.
